Cannot use screen action within the same screen

Cannot use screen action within the same screen

  

Hi,

Why we can't use screen action within same screen in web ?

Thanks in advance.

Hi,

Can you detail what your are trying to achieve?

The goal of screen actions is to react to some action on your screen like a button click or an onchange of a input.

Hi tBt,

for example  if you have screen action as 'Save', you cannot use that for two different buttons? Is that your question?

Please provide more details.

It is a conceptual decision.

Like Ana said, the purpose of a screen action is to provide a response to an user action in the user interface (web screen), like pressing a button, clicking a link, changing the selection on a combo box, etc.

In any case, while you can't call a screen action from within another screen action, you can call the same screen action from more than one place in the screen.

If you need to re-use logic, you can implement it in a Server Action and than call it from within one or more screen actions.

If it seems you need to call a screen action from another one, you should review your logic and user interface.

Cheers,

Eduardo

Here is the example :

I want to add Screen Action CalcDiscount into BuatInvoice Action, but it can't.

Instead, I need to make a screen action in Server Action to accomplish that.


Solution

Yes. You have to use a Server Action to implement this.

Solution

Yes, that is correct.

You cannot call a screen action inside an other screen action. But you can isolate the logic you want to reuse in a server action and than call it on both screen actions. That is the common practice for these scenarios.

Ic, ok thank you for the information :)

This Forge component can help tBt...

I'm reviving this thread, because there are situations where I want to reuse the logic that can't be included in a server action. For example, I might want to ajax refresh a portion of the screen when two different buttons are clicked.

I should just be able to drag a Screen Action into a Screen action and be done.

Please fix this. This is not very reusable code friendly.

That's Imho absolutely must-to have and easy to implement feature.
